deep learning studio container fails to get pulled

Accelerated Computing NGC GPU Cloud Docker and NVIDIA Docker
#1

This container

https://ngc.nvidia.com/catalog/containers/partners:deep-learning-studio

fails like so:

$docker pull nvcr.io/partners/deep-learning-studio:cuda9-2.5.0

Error response from daemon: Get https://nvcr.io/v2/partners/deep-learning-studio/manifests/cuda9-2.5.0: unauthorized: authentication required

I signed up at https://deepcognition.ai , the authors of deep learning studio, but do not know how to enter those credentials into the docker pull command.

In order to download this container you need to register with NGC at https://ngc.nvidia.com/signup and use that when you log in.
